A nuclear fallout shelter located near the V1 rocket launch site, built to protect against the expected fallout from Allied V-1 flying bombs. The shelter was constructed as part of the French nuclear defense strategy during the Cold War era. Its primary function was to provide a safe haven for French citizens in the event of a nuclear attack.
The facility was likely used in conjunction with France's nuclear-armed aircraft, which were authorized for temporary deployment by French President Emmanuel Macron in 2023. The V1 Feuerstellung Nr. 222 is a rare example of a nuclear fallout shelter in France, and its existence highlights the country's efforts to prepare for potential nuclear threats during the Cold War.
